What can I do for retina detachment? Please help!

Are you asking as a practitioner or generally. If a practitioner you would need to include more details including tcm diagnoses and supporting signs and symptoms, etc. If generally, you really should consult directly with a practitioner locally. Generally TCM is better at improving healing after western attachment procedures and in avoiding the problem to begin with (by improving fluids, etc.). A relevant study to give you an idea would be “effect of Chinese medicines on the subretinal fluid absorption after operation for retinal detachment”.
